The high potassium fraction contained in 8-4-16 is designed to provide excellent wear tolerance and stress tolerance, and is an ideal fertilizer for winter conditioning.
The controlled release provided by the meal based technology gives consistent feeding and turfgrass response for 8-10 weeks at recommended rates.
As with all GreenSpec products, be sure to water in thoroughly following application.
8-4-16 Endurance has all of the same great qualities as all GreenSpec products PLUS these unique qualities:
Formulated to revitalize and strengthen turf, as well as improve color. It conditions and improves depleted soils while protecting ground water from nutrient leaching and high heavy metal concentrations.
8-14-16 Endurance is the ideal fertilizer for promoting wear tolerance and stress resistance. Apply early or late fall to maximize overwinter survivability.
100% of the potassium source is Sulfate of Potash, derived from solar evaporation ponds.
It has the lowest salt index of any raw potassium source.Offers sustained, even feeding and color for 8-10 weeks, with less frequent mowing.
Nutrient release and subsequent plant uptake determined by microbial activity and will vary based on soil moisture, temperature, pH, and turfgrass species.
